Line fluxes, powers, and their ratios for our radiative-transfer calculations based on the ejecta models arising from He-star progenitors evolved with the nominal mass loss rate (Woosley 2019; Ertl et al. 2020). Quantities δė are fractional powers relative to the total decay power absorbed in the ejecta, while δL corresponds to the fractional luminosity relative to the total optical luminosity. Both are given as a percentage.
